[Qemu-devel] [PATCH v4 0/3] e1000: allow model/device_id selection on command line

[Qemu-devel] [PATCH v4 0/3] e1000: allow model/device_id selection on command line

[Gabriel L. Somlo]

    Allow selection of different card models from the qemu
    command line, to better accomodate a wider range of guests.

New in v4:

  - s/E1000Info_st/E1000Info/
  - s/E1000DeviceClass/E1000BaseClass/
  - keeping removal of 8257xx code as a separate third patch

Thanks,
  Gabriel

v3:

  - 1/3 and 2/3 from v2 now merged into a single patch (1/3), with:
      - s/TYPE_E1000/TYPE_E1000_BASE/ as suggested by Stefan
      - improved QOM-ification as suggested by Peter Crosthwaite

  - *OPTIONAL* patch to remove stale support for 8257xx (see commit blurb
    in patch 3/3 for details
    (this can be squashed on top of 1/3, but I'm including it separately
     here for clarity, and as an RFC).

v2:

  - moved check for 8257x out of the way of QOM, as suggested by
    Michael (patch 1/3)

  - resolved "Signed-off-by" misunderstanding and miscellaneous style
    issues (patch 2/3)

  - modified e1000 test to check for all supported models, as suggested
    by Andreas (patch 3/3). I used eepro100-test.c as an example for
    this change.

Gabriel L. Somlo (3):
  e1000: allow command-line selection of card model
  tests: e1000: test additional device IDs
  e1000: remove broken support for 82573L

Should this instead be "cpu_to_le16(edc->phy_id2)" ?

Same here, use "cpu_to_le16()" ?

If "Yes", then how about the "phy_reg_init[]" table ? It's an array
of uint16_t's with a bunch of statically defined elements, but gets
memove()'d in place during e1000_reset in cpu format, which may not be
appropriate if the host is a big-endian machine.

I'm primarily concerned about the correctness of my own patch set here,
but wondering if e1000.c might need additional work (e.g.  phy_reg_init[]
and friends) ? :)

Thanks much,

No, ->phy_reg[] is in host endian.

The hardware register accesses go through QEMU MemoryRegion.  The memory
regions are marked DEVICE_LITTLE_ENDIAN so the QEMU core device
emulation code handles the byteswapping for us (if necessary).  The
e1000 code itself operates in host endian.

The exception to this are the guest-memory DMA structures like the
descriptor rings.  Here we need to byteswap since we're reading/writing
guest memory ourselves.  Since your patch doesn't touch this you
shouldn't need to worry.

[Qemu-devel] [PATCH v4 3/3] e1000: remove broken support for 82573L

[Gabriel L. Somlo]

Currently, e1000 support is based on the manual for the 8254xx
model series. 82573x models are documented in a separate manual
(see http://www.intel.com/content/dam/www/public/us/en/documents/manuals/pcie-gbe-controllers-open-source-manual.pdf)
and the 82573L device ID no longer works correctly on either Linux
(3.14.*) or Windows 7.

This patch removes stale code claiming to support 82573L, cleaning
up the code base for the remaining 8254xx model series.
